Application led August 3, 1916. Serial No. 112,942.

To all 'whom it may concern:

Beit known that I, ALANsoN Mol). GEA?,

Elizabeth, in the county of Union, State of New Jersey, have invented certain new and useful Improvements in Chill-Plates, of which the following Vis a specication.

This invention relates to chill plates parclass of apparatus for molding waX and other material in which a series of narrow molds are set up in alternation with hollow chill plates, asv

exemplified in United States Letters Patent No. 653,235 granted to me July 10, 1900. Y

The invention relates particularly to certain improvements in the chill plates and method of circulating the water or other and uniform flow may be regulated and maintained and air pockets may be avoided. It also includes sim le and effective means for discharging mu dy and other deposits fromV the chill plates, time to time accumulate therein.

In the accompanying drawings:

Figure 1, is a side .elevation of a wax molding apparatus embodying the improved chill plates, partly in section, with some details omitted: f v

Fig. 2, a transverse section on line 2, 2, Fig. 1, showing one of the chill plates inY section: Fig. 3, an enlarged view of one corner of one of the chill plates, showing manner of connecting the cooling fluid pipes to the hottom thereof, and v Fig 4, a sectional view of some of the alternating molds and chill plates, on line 4, Fig. 2. 1

which the molds and chill Theaevi iii plates are held in alternation maybe a Vpress draulic cylinder 5, aemovable head 6, fixed `head 7 and side connecting bars 8. 9` indi-v cates legs or supports for the press. i Y

The molds 10 may be narrow open top frames provided with side ears 11 by which the. are supported on the sidebars .Y The also provided with side suppatent- .l

It has .been found that air pockets` are y Y {lates heretofore used, and that adgacent 'suc as the same may from ,comprising a hy- Y 12, as in my' before mentioned V in the` circulating spaces orv v'partsof the chill plates the wax in the molds will be indiferently or unsatisfactorily chilled, resulting in more orless imperfections in the cake. This difficulty is remedied by, and other advantages accrue-from, the improved chill plate of this invention, which is'lconstructed as follows. It is 'a narrow hollow plate, rectangular in form corresponding to the shape of the wax molds, or'other receptacle to be submitted to cooling effects, and having side wallsrl, 13 and lateral partitions 14. The outer partitions extend from the top 15 to within a short distance from the b0ttom'16,

and the intermediate one is connected'to the bottom, its upper end being a short distance from thetop, as shown at Fig. 2.V These chill plates with their supporting ears 12 areV preferably made integral, as castings. cooling fluid sup ly and dischar epipes pass up 4through theA ottom of the c ill plate to within a short distance from the top in the end chambers or passages. of the fluid is'downward from the inlet pipe 17, under the first partition 14, up Aand over the second partition and down and under the third one, and upwardly to escapel from the orice of the discharge pipe 18, which is water. To insure that all of the plates will be entirely filled and remainV full with the water' continuously moving it is found necessary,or very advantageous, to have the outmay be accomplished by contracting the end of pipe 18 into nozzle form as at 19, thus in-r` Y suring that more water may enterthe plates through inlet pipes 17 than can escape there-k from. A' smaller outlet pipe'might accom- Y but it 1s preferredtoV plish a like purpose, make the pipes of the samejsize andas large as possible,` hereafter appear. water, isf-quite' The pressure-iof" the VThe l forY aVA purpose that'will v100 or head underfwhich it is supplied,` r low and thefflow'throughthe plates The circulation v Y let orifice smaller than ,the inlet orifice; thisis slowand variations in the'quantities flowing through the ous reasons, likelyv toio'ccur. correction for thisl the pipes 17 and 18 are made vertically adjustable, and'by setting their upper. ends at suitable VVlevels the fiiow. v iY fthrough form and adequate to producethe desired,

various plates are, for vari- -1 Tov provide cooling effects in all of the molds. It may from the sides of said removed from the molds,

be necessary only to adjust one of the pipes, preferably the outlet pipe.

In the bottoms of each ofl the plates. are fitted screw-threaded reducing plugs 20, 20, through the centers of which the pipes 17 and 18 are screwed so as to extend a distancebelow the plugs. This provides means for setting the upper ends of the pipes in Y proper working levels, and when so set they are securely held by jamA nuts 21, 21. At and for some distance abovethe bottom of chill plates the pipes 17 and 18 are perforated with valve openings 23, which under ordinary working conditions are closed by the blank sides of sleeves 22, 22 closely litting over the pipes. These sleeves are securely held infthe plugs 20, 20 by being screwed therein, as shown, and they are provided vwith valve openings 2.4L arranged to aline with the openings 23 when the pipes are rotated about one-half a revolution from the positions indicated in Fig. 3. Operating handles 25 are attached to the pipes 17 and 18 at or near their lower ends. The valves 23, 24:` are set in open position when it is desired to drain water from, or to clean out the chill plates. In the latter case mud or other deposits may then be washedv out by suitable flooding so as to fall into a trough 26. This trough is preferably formed of concrete. It is large enough to extend under the whole of the apparatus to receive and collect all water discharges whether from the discharge pipes 18 or leakage from any part of the` apparatus. Each inlet pipe 17 is connected to a common water ysupply pipe 27 by means of flexible hose 28; this provides for permanent water connections tothe chill plates, leaving them free to slide on the bars 8 asthe press is manipulated to place the parts in operative position and to remove the chilledwax cakes.

Each bar 8 has a'rail 29 seouredto it by being fastened to bolted studs 30 extending bars. YA carriage or platform truck31 travels on the rails 29 being guided and supported thereon by grooved wheels or pulleys 32. This carriage 31 receives thecakes of set wax as they are commencing at onev end of the apparatus, receiving the wax cakes las they are removed from the successive molds and moved to or beyondV the other end, as indicated in Fig.v 1, to have itsload of cakes taken away for packing.V This saves considerable. time required in'the manipulation of the press.

33l -designates a wax spout for lillingthe molds with meltedwax.Y 34 is.v a drain pipe for the trough. l

There is considerable advantage in con-YY nectingthe inlet and outlet pipes of the Y cooling iuid to thei bottoms of the chill plates. All liquid dischargesA under thew before mentioned patent the discharge pipes are at the side of the press and discharge into a trough locatedl also at the side of the press.
